Eec1940097993ac318d449068c3f7909


Abstract: The Topic Maps Constraint Language (TMCL) is used to create a schema for Topic Maps. Creating a schema is possible by using CTM templates, specified in the TMCL draft. Onotoa is a visual editor for TMCL. Instead of writing CTM file, it is possible to create the schema using diagrams.

This tutorial is part oft the session Tutorials at the TMRA 2009 conference.



Onotoa and getting started with TMCL

Onotoa is the Eclipse-based ontology editor for Topic Maps. It has a graphical UML-like interface, an export function for the current TMCL-draft and a XTM export described here. In the latest version Onotoa provides you with a “business view” mode for your schemas. This features supports you in the communication with your customers: you will concentrate on sketching the customers domain – not on explaining any TMCL details.

To get started with Onotoa the Onotoa handbook is very helpful. You can download the current version of the handbook here.

There are also free hard copies of the Onotoa handbook available. If you like to have one of these copies, please drop us a note. We will send the handbook to you for free.
